' 2 Claims.

This invention relates to containers generally. More specically this invention relates to containers having a false bottom which is arranged to be withdrawn for the purpose of eX- pelling the contents from the container.

An object of this invention is to provide a container with a closely fitting false bottom arranged to be readily withdrawn from the container for removing the material contents of the container.

Another object of this invention is to provide a container with a closely fitting false bottom, arranged to be readily withdrawn, having a small vent-like opening adapted to be opened when the false bottom is being withdrawn from the container.

Still another object of this invention is to provide a container for paint or painting materials in which it is necessary to use all of the contents of the container, with a closely fitting withdrawable false bottom having a member cooperating therewith for opening a vent in the false bottom to facilitate the withdrawal of the false bottom.

Other and further objects of this invention will be apparent to those skilled in the art to which this invention pertains from the following specification and the appended claims.

In the paint industry employing colors in oil which are to be mixed with lead in oil or other pigments, such as zinc oxide, zinc sulfide, titanium dioxide and the like, it is necessary to use a certain quantity of colors in oil in a certain quantity of the lead in oil or other pigment employed in order to produce paint of a predetermined color shade. These colors in oil are accurately blended and distributed in small containers of predetermined sizes. In order to produce paint of a certain color shade, the contents of each of these containers must be mixed with a certain quantity of pigment. It is, therefore, essential that all of the colors in oil contents of the container be used in order that the variation in the color shade of the paint produced be kept at a minimum.

In accordance with this invention, a container is provided with a reinforced false bottom which is arranged to be withdrawn from the container through the mouth thereof and simultaneously clean the inner walls of the container. After the false bottom is withdrawn from the container the material which was cleaned from the Walls is removed and used. This false bottom may be made substantial enough to be used as a paint mixer in cases where the container is employed for the purpose of distributing colors in oil. Another feature of this invention is to provide a vent opening arrangement to function to permit air to enter between the false bottom and the bottom of the container as the false bottom is withdrawn. This permits easy and efficient withdrawal of the false bottom and also facilitates more complete removal of the material from the inner walls of the container.

This invention will be more readily understood by reference to the following specification in conjunction with the accompanying drawing, in which:

Fig. 1 illustrates the container in vertical cross section;

Fig. 2 is a fragmentary detail view of the false bottom of the container, and

Fig. 3 is a fragmentary cross sectional View of a modified form of this invention.

Reference numeral 1 of Fig. 1 of the drawing designates a container of metal, glass or other materials suitable for containers. A cover 2 provided with a gasket 3 is fitted to close the mouth of the container 1. A false bottom comprised of a stiff cardboard bottom section 8 and a leather section 7 is placed directly over the bottom of the container. In cases where the container is used for colors in oil the section 8 of the false bottom may be made of diiferent materials, such as a hard rubber, cardboard or cellular material impregnated with phenol condensation products or similar compounds insoluble in the contents of the container. When the section '7 of the false bottom is snugly fitted into the container so that the contents thereof do not come in contact with the section 8 it is not necessary to impregnate this latter section to prevent absorption of any of the contents of the container. The section 7 is preferably made of thin leather which may be cemented to the section 8 in its central zone. The edges of the section 7 are preferably feathered and curved upward in order to facilitate the removal of any material from the Walls of the container when the false bottom is withdrawn.

A bail member 4 of metal or cord impregnated with resinous material or phenol condensation products is attached to the false bottom. ,Sections 5 and 6 of this bail member 4 are bent and pressed into the portion 8. If the bail 4 is made of wire the ends 12 and 13 may be made to protrude upward through the false bottom. In cases where the bail is made of cord the sections 12 and 13 of the bail may be caused to` move downward relative to the false bottom during the withdrawal of this bottom and small air openings adjacent to these sections thus provided. This may be more clearly seen by reference to the detail Fig. 2 of the drawing in which the reference numerals designate the same parts as in Fig. 1.

A slightly modified form of this invention is illustrated in Fig. 3 of the drawing wherein the bottom la of the container 1 is provided with a small protrusion 1b. Small openings in line with the projecting section lb are provided to the removable bottom. As the false bottom is withdrawn by the member 4 the vents which are aligned with the section 1b are opened.

From the foregoing specification it is seen that other modifications of this invention may be made without departing from the scope and spirit of this invention, and that, therefore, it is not desired to limit this invention to the exact details as set forth except in so far as those details are defined in the appended claims.

What I claim and desire to secure by Letters Patent of the United States is:

1. In combination, a container, a closely tting false bottom positioned in said container, means for withdrawing said false bottom, said means comprising a member projecting through openings formed in said false bottom said member having sections pressed into said false bottom, sections of said member in engagement with said false bottom being adjusted to enlarge said openings as said false bottom is withdrawn.

2. In combination a container, a closely fitting false bottom positioned in said container, a wire member for withdrawing said false bottom, said wire member being embedded in said false bottom so that sections thereof enlarge one or more openings in said false bottom during the withdrawal thereof from said container.
